Application filed. Octo er a, 1920. Serial No; 415,557.

To all who m it may concern:

I 3e t known that I, LoUIs G. BAYRE'R, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Yokes for Diesinking lWIachines, of which the following is a specification.

This invention relates to work supports and particularly to a work-supporting meniber or yoke adapted to be secured to'a block or piece of work to provide a supporting hold thereon. It is the primary object of the invention to provide such a member Fig. 3 is a longitudinal section thereof taken on the line 3 3 of Fig. 2.

Fig. 4: is a crosssection taken on the line so 4=4l of Fig. 3.

The work support comprising the present invention is adapted particularly for use in the machine illustrated in my Patent No. 1,329,358, Feb. 3, 1920, although it will be understood that the invention is not necessarily so limited. In the structure illustrated I have provided two adjustable arms adapted to engage a piece of work at opposite sides thereof. Means are provided for securing the arms in work-engaging position and other means are preferably provided for engaging the face of the work to secure the work support rigidly thereto. A further means, preferably comprising an'integral projectionqon the body portion. of the support. is provided for engagement by' a supporting crane. that the structure shown isillustrative of the invention and may be modified within the scope of the appended claims.

Referring to "the drawing by reference characters, 1 designates the frame of a milling machine having a work table 2 slid'ably mounted on a saddle 3 also slidably mounted on avertically adjustable knee 4:. Thework which may be readily and easily secured to It will be understood IV is mounted onthe table and is adapted also to have the major portion of its weight supported by a pair of articulated arms 5' pivoted to the frame 1. A vertically adjustable rod 6 mounted in the'end of each arm 5 forms an adjustable supporting 'connection between each arm and-the WO'rkmThe" means, shown in detail in Fig. 2, b'y'whicl 1 eachrod 6 is adapted to engage andrsupport the work comprises the present invention 65- which will-now be described;

The work support oryoke comprises in brief a body'member 7 and a pair of relatively adjustable work-engaging arms '8. These arms are preferably arranged in. an overlapping relation and are adapted to be i relatively adjusted longitudinally to ,permit; the engagement of different sized pieces of work. Each arm is provided with a right angular extension}? having 'a work -engaging pin 10 in the end thereof. Asameans'for] locking the arms in workeengaging position, I have illustrated each arm as provided with a plurality of transversely extending'teeth 11 adapted to be engaged by a similarly toothed member 12 held in thebody mem her? by means of apairof'set screws 13 threaded into the body member and socketed into the member 12. A pin 14 mounted in p the end of each arm 8 prevents the arm from sliding outof the body member. I also provide supplemental work-engaging means herein shown as set screws 15 on opposite sides of the arms 8. .An integral projection 16 on the body member 'providesa means adapted to be directly engaged by the supporting rod 6. I

Each work; support is secured to its end of the work as follows. A pair ofjholes is drilled in oppositesides ofthe work ta receive the pins 10. The setscrews13 are f backed out to release theengagement of the members 12wi'th the teeth l'lof'the arms 8, thusleaving the arms free to slide with n in the-body member 7. Theyoke is then 'placedover the, end of the work asshown in Fig. 1 and the extensions '9 are drawn-f tightly into engagement: with the sides of 3 I a manner to hold the yoke in the prop ersu'p, r10
